NAME

       vftovp  -  convert  virtual  font  (vf) files to virtual property lists
       (vpl)


SYNOPSIS

       vftovp  [  -charcode-format=format  ]   [   -verbose   ]   vf_name[.vf]
       tfm_name[.tfm] [ vpl_name[.vpl] ]


DESCRIPTION

       This  manual page is not meant to be exhaustive.  The complete documen-
       tation for this version of TeX can be found in the info file or  manual
       Web2C: A TeX implementation.

       The  vftovp  program  translates a (program-oriented) virtual font file
       and its accompanying TeX font metric file to a  (human-oriented)  prop-
       erty  list  file.   Thus, the virtual font can be edited, and its exact
       contents can be displayed mnemonically.  It also serves  as  a  VF-file
       validating program; if no error messages are given, the input files are
       correct.

       The filenames are extended with the appropriate extension if necessary.


OPTIONS

       The  argument  format to -charcode-format specifies how character codes
       are output in the VPL file.  By default, only letters  and  digits  are
       output using the C integer code (i.e., in ASCII); the others are output
       in octal.  (Unless the font’s coding scheme starts with TeX math sy  or
       TeX  math  ex,  when all are output in octal.)  If format is ascii, all
       character codes that correspond to graphic characters, besides the left
       and right parentheses, are output in ASCII.  On the other hand, if for-
       mat is octal, all character codes are output in octal.

       Without the -verbose option, vftovp operates silently.  With it, a ban-
       ner and progress report are printed on stdout.


ENVIRONMENT

       vftovp  looks  for  vf_name using the environment variable VFFONTS.  If
       that is not set, it uses the variable TEXFONTS.  If that is not set, it
       uses the system default.

       See tex(1) for the details of the searching.

AUTHORS

       Donald  E.  Knuth  wrote the program, based in part on an idea of David
       Fuchs, starting with the code for tftopl(1).  Karl Berry adapted it for
       compilation with web2c.
